Investigation of diseases in poultry, K. F. Pernot {Oregon Sta. 

 Bid. OJf., _i'j^. 2Ji,Jig.s. 4). — The uuthor made a study of avian tubercu- 

 losis in poultiy. Experiments in inoculating- guinea pigs with tuber- 

 culous material from the intestines and liver of a diseased hen gave 

 negative I'esults. In one case where 6 hens died of tuberculosis one 

 was examined and found affected with a generalized form of the dis- 

 ease. The digestive tract was evidently the original focus of infection 

 in this case, as shown by the numerous tubercles in the intestinal 

 walls. These tubercles ultimately break down, and the disease may 

 therefore be spread in the intestinal passages. It is recommended 

 that all fowls which die of tuberculosis should be deeph' buried or 

 burned. The author studied also one case of tuberculosis of a hen's leg. 



In the treatment of catarrhal roup, the author obtained good results 

 from the use of a 2 per cent sokition of permanganate of potash and 

 water. In administering this treatment the head of the fowl was 

 plunged into the solution and held there for a short time. The result 

 of this immersion is ordinarily violent sneezing, which forces the 

 solution through the nasal passages. The same solution may be 

 diluted with 4 times its bulk of water and given to the fowls to drink. 



Favus of fowls may be treated b}- removing the scales from affected 

 birds and applying an ointment made of vaseline and 2 per cent car- 

 bolic acid. The treatment recommended for scabies of poultry consists 

 in removing loosened scales by soaking in warm water and soap and 

 the subsequent application of an ointment made of balsam of Peru, at 

 the rate of 1 or 2 drams to 1 oz. of vaseline. 



The author reports serious losses among young chickens, especiall}' 

 incubator chickens, from pneumonia and congestion of the lungs.* 

 These diseases were apparentl}" brought about from overcrowding in 

 the brooders and from exposure to cold when allowed to come out of 

 the brooder houses. As a i-emedy for this difficulty, the author recom- 

 mends any device which will prevent the young chickens from hud- 

 dling too closely together and becoming overheated. In one instance, 

 where a device of this kind was used, 99 per cent of the chickens were 

 raised. A rather heavy loss of incubator chickens was occasioned in 

 some parts of the State by indigestion, due to improper feeding and 

 to feeding too soon after hatching. 



Tetanus, E. Mathews {Jour. Camp. Med. and Vet. Arch., 21 {1900), No. 12, j)p. 

 741-74-^) ■ — The author treated 4 cases of tetanus by hypodermic injections of woorara 

 with good results in 2 cases, while in the other 2 cases the quality of tlie drug M-as 

 believed to be inferior. 



The source of tuberculosis in farm animals, K. R. Dinwiddik {Arkansas Sta. 

 Bid. G3, popular cd., ptp. 69-73). — A brief iiopular form of Bulletin 60 (p. 1084). 



The value of serum reactions for the early diagnosis of tuberculosis, S. 

 Arloing and P. Coukmont {Deut. -Med. Wchnsdir., 26 {1900), No. 4S, pp. 766-769). —
